Brief Summary
This laboratory study is looking at stored tumor samples in young patients with brain tumors. Studying samples of tumor tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer.

Tumor/Tissue Sample
Tumor material collected prospectively from a clinically well characterized patient cohort
Eligibility Criteria
Participants will all brain tumor types will be included with a focus on medulloblastoma, HGNET, CNS embryonal tumors, gliomas, ependymoma, CPC and ATRT tumors. All studies will be conducted using tumor material collected prospectively from a clinically well characterized patient cohort.
You may qualify if:
- Tumor may be primary, progressive or recurrent CNS tumor including brain and/or spine. All tumor types will be included with a focus on medulloblastoma, HGNET, CNS embryonal tumors, gliomas, ependymoma, CPC and ATRT tumors. Low grade gliomas are currently very challenging to culture and implant but if techniques mature these will also be included. Although rare, patients with ATRT may present with a primary renal and CNS tumor. In these instances samples will be collected from both the kidney and CNS tumor for analysis if available.
- Tumor may be collected at surgery prior to histologic confirmation
- Age less than 40 years at the time of initial diagnosis.
- Enrollment in the current version of the institution's banking protocol
You may not qualify if:
- Diagnosis of tumor outside the central nervous system.
- Age greater than or equal to 40 years at the time of diagnosis
